Transmission of uplink control information in wireless systems

ABSTRACT

Future LTE systems will support massive carrier aggregation that necessitates transmission of a large number of acknowledgement signals (HARQ-ACKs) in response to downlink data transmitted over multiple component carriers. Methods and apparatus for efficiently transmitting HARQ-ACK and periodic channel state information (P-CSI) bits over the PUCCH include decoding DCI received on a PDCCH, the DCI including a flag indicating a resource value from a plurality of PUCCH resource values for a PUCCH resource. UCI is encoded for transmission using the PUCCH resource, the UCI including a hybrid automatic repeat request acknowledgement (HARQ-ACK) in response to data received on a PDSCH. The PUCCH resource is selected from a plurality of PUCCH resources based on a payload size of the UCI and the resource value. Transmission power for transmitting the UCI is set using the PUCCH resource based at least on the payload size of the UCI.

TECHNICAL FIELD

Embodiments described herein relate generally to wireless networks andcommunications systems. Some embodiments relate to cellularcommunication networks including 3GPP (Third Generation PartnershipProject) networks, 3GPP LTE (Long Term Evolution) networks, and 3GPPLTE-A (LTE Advanced) networks, although the scope of the embodiments isnot limited in this respect.

BACKGROUND

In Long Term Evolution (LTE) systems, a mobile terminal (referred to asa User Equipment or UE) connects to the cellular network via a basestation (referred to as an evolved Node B or eNB). Previous releases ofthe LTE specifications supported communication between the UE and theeNB over either a single carrier for both the UL (uplink) and DL(downlink) in the case of TDD (time division duplex) mode or separate ULand DL carriers in the case of FDD (frequency division duplex) mode.LTE-Advanced extended the capabilities of LTE systems with support ofcarrier aggregation, where up to five CCs (component carriers) areaggregated in order to support wider transmission bandwidths up to 100MHz. The CCs may also be referred to as serving cells. One CC is termedthe Pcell (primary cell) and the other CCs are referred to as SCells.Subsequent releases of the LTE specification will provide support for upto 32 CCs. A primary concern of the present disclosure is efficienttransmission of data acknowledgement signals by a UE to an eNB inresponse to DL data transmissions over a large number of DL CCs.

DETAILED DESCRIPTION

FIG. 1 illustrates an example of the components of a UE 400 and a basestation or eNB 300. The eNB 300 includes processing circuitry 301connected to a radio transceiver 302 for providing an air interface. TheUE 400 includes processing circuitry 401 connected to a radiotransceiver 402 for providing an interface. Each of the transceivers inthe devices is connected to antennas 55.

A UE transmits a number of control signals to the eNB, referred to asuplink control information (UCI). The current LTE standards specify thata UE transmits a hybrid automatic request repeat acknowledgement(HARQ-ACK) signal over the uplink (UL) in response to data packetreception over the downlink (DL). Depending on whether the data packetreception is correct or incorrect, the HARQ-ACK signal has an ACK or aNAK value, respectively. The UE transmits a scheduling request (SR)signal to request UL resources for signal transmission. The UE transmitschannel state information (CSI) reports that include a channel qualityindicator (CQI) signal to inform the eNB of the DL channel conditions itexperiences, enabling the eNB to perform channel-dependent scheduling ofDL data packets. The UE also transmits precoder matrix indicator/rankindicator (PMI/RI) signals to inform the eNB how to combine thetransmission of a signal to the UE from multiple eNB antennas inaccordance with a Multiple-Input Multiple-Output (MIMO) principle. Anyof the possible combinations of HARQ-ACK, SR, CQI, PMI, and RI signalsmay be transmitted by a UE jointly with data information in the physicaluplink shared channel (PUSCH), or separate from data information in thephysical uplink control channel (PUCCH). The number of ACK bits for onUL subframe will depend on the number of DL carriers and the TDDconfiguration (in case of TDD). The maximum HARQ-ACK codebook size inthe uplink by one UE in one subframe for DL CA of up to 32 CCs is atleast 64 bits for frequency-division duplex (FDD) cells and can beselected from a set of values up to 638 bits for time division duplex(TDD) cells. Periodic CSI (P-CSI) bits for up to 32 CCs may reach to 352bits as well. HARQ-ACK and CQI transmission may need to occur in thesame sub-frame o then PUCCH in the absence of data transmission from aUE.

The different formats of the PUCCH previously defined by the LTEspecifications (i.e., formats 1, 2, and 3) are not capable of conveyingthe amount of UCI necessary for up to 32 CCs as described above. A newPUCCH format, referred to herein as format X, for carrying this amountof UCI is illustrated in FIG. 2. As used herein, the term “PUCCH formatX” refers to a PUCCH format that carries a larger amount of uplinkcontrol information (UCI) bits than format 3 as defined in the LTEspecifications (i.e., more than 22 bits). The format X as illustrated isa PUSCH-like PUCCH structure with one demodulation reference signal(DMRS) per slot and may be without orthogonal cover codes (i.e., codedivision multiplexing or CDM) for data/control symbols. Shown in thefigure are two slots separated in frequency where one slot containssymbols D1 through D6 for carrying UCI and the other contains symbols D7through D12 for carrying UCI. Each slot also has a single referencesignal RS (i.e., a DMRS). The format may be designed to preserve thesingle-carrier property of the single carrier frequency-divisionmultiplexing (SC-FDM) used in the uplink and avoid increasing the cubicmetric (CM) of concurrent transmissions of HARQ-ACK/SR and multi-CCs CQIbits when these UCIs are multiplexed in the same PUCCH.

Described herein are techniques for concurrently transmitting multipleUCIs using a high-capacity PUCCH format such as format X in a massive CAapplication including simultaneously transmitting periodic CSI (P-CSI)bits together with HARQ-ACK/SR bits in a multi-CC scenario. The issuesaddressed by the described techniques, which take into account thedifferent UCI target block error rate (BLER) requirements (1% BLER forHARQ-ACK and 1˜5% BLER for CQI), include: how to select a proper PUCCHchannel out of a set of configured resources to carry UCI bits withguaranteed performance and maximized payload size, how to design thechannel coding scheme to differentiate the UCI transmission taking intoaccount the different performance targets to improve UL throughputperformance, and whether and how to implement conditional suspension ordropping of partial UCI in some cases (e.g., power limited cases).

The described techniques provide resource allocation methods for the newPUCCH format X, a channel selection algorithm when transmission of UCIshappens in a single UL subframe, such as multi-CCs HARQ-ACK/SR togetherwith multi-CCs CSI bits; the use of joint coding or separate coding formultiple UCIs transmission on a PUCCH format X resource that isconfigurable in an explicit manner or implicit manner; criteria toenable UE determines itself whether to transmit deprioritized UCI ornot, involving either a ratio of PUCCH resources for HARQ-ACK/SR and/orRI symbols; and various solutions to implement joint coding and separatecoding scheme, including power control equation design for joint codingas well as resource elements number determination for separate coding tominimize the UCI overhead taking different HARQ-ACK and P-CSIperformance targets into account for each channel coding scheme.

In one embodiment, a plurality of PUCCH resources may be configured byhigher layers for UCI (including HARQ-ACK, Scheduling Request (SR), CSI,or a combination thereof) on PUCCH. In one example of this embodiment,there may be at least two different sets of PUCCH resources on UL PCellor PUCCH SCell or pSCell. A first set of PUCCH format X resources aresemi-statically signaled by radio resource control (RRC) signaling forUE configured with more than 5 CCs. In addition, a second set of PUCCHresource are allocated for multi-CCs P-CSI transmission. Particularly,the second set of PUCCH resources may be a subset of the first set ofPUCCH format X resources to save UL control overhead. Alternatively, thesecond set of PUCCH resources may be different PUCCH format X resourcesor a combination of PUCCH format 3 resource and new PUCCH format Xresources. In an example of this embodiment, a UE may be configured withtwo PUCCH resources having different payload size in the second set. Asthe UE only reports P-CSI for these activated CCs, configuring twoPUCCHs with different capacities can maximize the spectral efficiency.The PUCCH with the larger payload size (e.g., PUCCH format X) is usedwhen the number of activated CCs is larger; While, UE can select thePUCCH (e.g. PUCCH format 3) with smaller payload size when a smallamount of CCs are activated. An alternative is to tie the PUCCH channelselection to the uplink hybrid ARQ ACK/NAKs such that the PUCCH withlarger capacity is selected only when HARQ-ACK bits are transmitted.

FIG. 3 illustrates an example procedure executed by a UE to select aPUCCH resource. The UE starts at stage S0 and receives configurationinformation as whether simultaneous PUCCH and PUCCH transmission ispermitted at stage S1. At stage S2, whether there is to be concurrenttransmission of HARQ-ACK and P-CSI bits in a single UL subframe. If not,one of a first set of PUCCH resources that include format X resourcesfor HARQ-ACK bits and 1-bit positive/negative SR or one of a second setof PUCCH resources for P-CSI bits without HARQ-ACK/SR bits is selectedat stage S3. The UE could select which PUCCH format X resource to usebased on a dynamic indicator IE in the detected downlink controlinformation (DCI) formats. In addition, dynamic indication of PUCCHformat X resources for HARQ-ACK bits can be done by using additionalrelative or explicit dynamic indication to select actual PUCCH resourcesout of the set of implicit/explicitly reserved (e.g., semi-staticallyreserved) resources. In case of collision between at least a periodicCSI report and an HARQ-ACK in a same subframe, the UE behaves asfollows. If the UE is configured by higher layers with simultaneousPUCCH and PUSCH transmissions as determined at stage S4 or the UE iscapable of multi-cluster PUSCH-withCC transmission as determined atstage SC, then, if there is no scheduling PUSCH as determined at stageS5, the HARQ-ACK is transmitted in the determined PUCCH resource of thefirst set and the P-CSI is transmitted in the second PUCCH resource atstage S8 using two separate precoders or a single DFT precoder.Otherwise, the HARQ-ACK is transmitted in the determined PUCCH resourceof the first set and the P-CSI is transmitted in the PUSCH at stage S7using two separate DFT precoders. Otherwise, the P-CSI is multiplexedwith the HARQ-ACK in the selected PUCCH resource at stage S9. The PUCCHresource selection may be achieved by implicit rule such as the PUCCHresource with a larger capacity, the determined PUCCH resource out ofthe first set or the one of second set of PUCCH resources, or the PUCCHwith the smallest UCI capacity but still able to accommodate the totalbit numbers of all UCIs. Alternatively, a reserved PUCCH resource can beindicated explicitly via signaling to the UE (e.g. RRC signaling), or bya combination of implicit and explicit signaling. In addition, forsimultaneous transmission of multi-CCs HARQ-ACK and multi-CCs P-CSIusing PUCCH format X, the maximum allowed P-CSI payload may be RRCconfigurable. Dropping the P-CSI report or truncation of the leastsignificant bits of the CSI report may be used in case theRRC-configured allowable maximum CSI payload is smaller than the numberof CSI bits in a subframe.

Various schemes may be used to transmit a combination of HA RQ-ACK/SRbits and multi-CCs P-CSI in one selected PUCCH in a subframe as shown atstage S9 in FIG. 3. In one example scheme, referred to herein as scheme1, joint coding is employed such that HARQ-ACK and channel qualityinformation (CQI) bits for the P-CSI report are jointly encoded priorto, transmission as illustrated in FIG. 4. The HARQ-ACK/SR bits and CQIbits are combined by multiplexer 2000, encoded by tail-bitingconvolutional coder (TBCC) 2010, and interleaved by channel interleaver2020.

In some embodiments, power control for PUCCH transmission may beimplemented by the UE as a function of the payload size and whether ULtransmit diversity is enabled or not. In addition, the number ofresource blocks (RBs) of the selected PUCCH resource N_(RB) ^(PUCCH) maybe also considered as a factor so that:h(n _(HARQ) ,n _(SR) ,n _(CQI))=f(N _(RB) ^(PUCCH) ,n _(HARQ) ,n _(SR),n _(CQI))where no corresponds to the number of information bits for the channelquality information; n_(SR)=1 if subframe i is configured for SR for theUE not having any associated transport block for UL-SCH and otherwisen_(SR)=0, and n_(HARQ) is the number of HARQ-ACK bits sent in thesubframe.

In one embodiment, to differentiate HARQ-ACK and P-CSI performancetargets when the UE transmits HARQ-ACK/SR and periodic CSI, the powerlevel may be adjusted by utilizing power control based on the actualinformation bits carried in PUCCH format X as follows:

${P_{PUCCH}(i)} = {\min\begin{Bmatrix}{{P_{{CMAX},c}(i)},} \\\begin{matrix}{P_{0{\_ PUCCH}} + {PL}_{c} + {h\left( {n_{CQI},n_{HARQ},n_{SR}} \right)} +} \\{{\Delta_{F\_ PUCCH}(F)} + {\Delta_{T \times D}\left( F^{\prime} \right)} + {g(i)}}\end{matrix}\end{Bmatrix}}$where P_(CMAX,c)(i) is the configured maximum UE transmit power definedin subframe i for the serving cell, the parameter Δ_(F_PUCCH) (F) isprovided by higher layers corresponding to a PUCCH format if the UE isconfigured by higher layers to transmit PUCCH on two antenna ports thevalue of Δ_(TxD)(F′) is provided by higher layers and otherwiseΔ_(TxD)(F′)=0, and h(n_(CQI), n_(HARQ), n_(SR)) is a PUCCH formatdependent value. In one example of this embodiment, h(n_(CQI), n_(HARQ),n_(SR)) may be determined as follows:

h(n_(HARQ), n_(SR), n_(CQI)) = a + b * 10 * log  10((n_(HARQ) + n_(SR) − 1) ⋅ β + n_(CQI) ⋅ α) − 10 * log  10(N_(RB)^(PUCCH))

where α and β may be configured by higher layers for a UE orpredetermined by specification. Example values for α and β are:

α=1, β=1 if presence of HARQ-ACK and/or SR and otherwise0<α<1, β=0, and

a=−14 and b=1.

In another example of this embodiment,

${h\left( {n_{HARQ},n_{SR},n_{CQI}} \right)} = {{10*\log\; 10\left( \frac{n - 1}{K} \right)} - {10*\log\; 10\left( N_{RB}^{PUCCH} \right)}}$where: n=n_(HARQ)+n_(SR) n_(CQi); K=22 or 23 or 25.Alternatively, h(n_(CQI), n_(HARQ), n_(SR)) may be determined usingfollowing equation:

h(n_(HARQ), n_(SR), n_(CQI)) = a + ((n_(HARQ) + n_(SR) − 1) ⋅ β + n_(CQI) ⋅ α)/b − 10 * log  10(N_(RB)^(PUCCH))The following are example values:

α=1, β=1 if presence of HARQ-ACK and/or SR and otherwise 0<α<1, β=0, and

a=−2 or −1 and 10≤b<15

In case the transmission of HARQ-ACK feedback coincides withtransmission of SR with or without CSI/RI bits, the SR bit (1=positiveSR; 0=negative SR) may be appended at the start or end of the sequenceof concatenated HARQ-ACK bits or may be appended at the start or end ofthe sequence of concatenated CSI bits when there is no HARQ-ACK bits(i.e. concurrent transmission of P-CSI and SR without HARQ-ACK). In oneembodiment, a method is provided for a UE to suspend/drop CSItransmission if one of two following conditions is met:

1) Condition 1: Combined HARQ-ACK and CSI payload is smaller than apredetermined value L.

2) Condition 2: Ratio of CSI payload over HARQ-ACK payload is smallerthan a predetermined value. Condition 1 is intended to avoid operationwith very large code rates which may not ensure target receptionreliability, even if UE can substantially increase transmission power(at the cost of additional interference). The motivation of Condition 2is that multiplexing many CSI bits with few HARQ-ACK bits is notdesirable in terms of required power.

In another scheme, referred to herein as scheme 2, separate coding isemployed such that different coding rates for the control information(e.g. HARQ-ACKISR vs. multi-CCs period CSI) on PUCCH using PUCCH formatX are achieved by allocating different number of resource elements (REs)for coded symbols transmission. FIG. 5 illustrates an example ofseparate coding where HARQ-ACKJSR bits, CQI bits, and RI bits areseparately encoded by tail-biting convolutional coders (TBCC) 5030, ratematching performed by stage 5020 and mapped to resource elements (REs)by stage 5010. The number of coded symbols is determined by stage 5000.

In one embodiment, three parameters β_(offset) ^(HARQ-ACK), β_(offset)^(RI) and β_(offset) ^(CQI) may be configured by higher layers,respectively. Alternatively, a set of offset values β_(offset)^(HARQ-ACK) for different HARQ-ACK codebook sizes may be configured orimplicitly derived for the number of HARQ-ACK coded symbol calculationwith accounting for the channel coding gains and avoid overestimation ofthe HARQ-ACK resources.

In one embodiment, two values may be configured as β_(offset,1)^(HARQ-ACK), β_(offset,2) ^(HARQ-ACK). The smaller value β_(offset,1)^(HARQ-ACK) is used when HARQ-ACK bits number is larger than apredefined or signaled threshold; otherwise, the larger valueβ_(offset,2) ^(HARQ-ACK) is used to guarantee the DTX detectionperformance at eNB side. In another example, one offset value for eachHARQ-ACK codebook size may be provided for the UE by higher layers byhigher layer signaling. Alternatively, these values may be derived fromthe one signaled for a reference HARQ-ACK codebook size (e.g. 22 bits),no additional signaling is required. For example, a factor SF (0) may beintroduced for this purpose and used in the determination of HARQ-ACKand RI resources in order to account for the TBCC coding gain over therepetition code for a HARQ-ACK and RI payload of 0 bits. The valuesβ_(offset) ^(HARQ-ACK) or β_(offset) ^(RI) in the equations set forthbelow may be values after applying the factor.

Example methods are described below for stage 5000 in FIG. 5 todetermine the number of coded bits for different UCIs multiplexed on aPUCCH, taking into account the RI payload is known at both the eNB andthe UE. In a first embodiment, when UE transmits HARQ-ACK bits, SR bitsor rank indicator (RI) bits, it shall determine the number of codedsymbols Q′_(UCI) for HARQ-ACK or rank indicator as

$\begin{matrix}{Q_{UCI}^{\prime} = {\min\left( {{{ceiling}\left( \frac{O_{UCI} \cdot M_{sc}^{PUCCH} \cdot N_{symb}^{PUCCH} \cdot \beta_{offset}^{PUCCH}}{O_{{CQI} - {MIN}}} \right)},T_{UCI}} \right)}} & (1)\end{matrix}$where O_(UCI) is the number of HARQ-ACKISR bits including CRC bits or RIbits; M_(SC) ^(PUCCH) is the bandwidth for selected PUCCH in the currentsubframe expressed as a number of subcarrier, and N_(symb) ^(PUCCH) isthe number of SC-FDMA symbols in the current PUCCH transmissionsub-frame given by N_(symb) ^(PUCCH)=(2(N_(symb) ^(UL)−1)−N_(SRS)),where N_(symb) ^(UL) denotes number of SC-FDMA symbols in an uplinkslot; N_(SRS) is equal to 1 if UE is configured to send PUCCH and SRS inthe same subframe for the current subframe, or if the PUCCH resourceallocation for the current subframe even partially overlaps with thecell-specific SRS subframe and bandwidth configuration, or if thecurrent subframe is a UE-specific Type-1 SRS subframe, or if the currentsubframe is a UE-specific Type-0 SRS subframe and the UE is configuredwith multiple TAGs. Otherwise N_(SRS) is equal to 0; O_(CQI-MIN) is thenumber of CQI bits including CRC bits assuming rank equals to 1 for allserving cells for which a periodic CSI report is configured. ForHARQ-ACK information;β_(offset) ^(PUCCH)=β_(offset) ^(HARQ-ACK)/β_(offset) ^(CQI),for RI bits:β_(offset) ^(PUCCH)=β_(offset) ^(RI)/β_(offset) ^(CQI)·, andfor CQI and/or PMI information:Q′ _(CQI) =N _(symb) ^(PUCCH)·β_(offset) ^(PUCCH) −Q′ _(RI).

For multiple UCI signals, different thresholds T_(UCI) may be predefinedvalues applicable to all UEs or they may be signaled to the UE throughhigher layers signaling for different UCI transmission in a subframe.T_(HARQ-ACK) denotes the threshold for HARQ-ACK bits; while T_(RI)denotes threshold for RI bits. Various T_(UCI) values may include one ormore following values:T _(ACK) =X·M _(SC) ^(PUCCH), where X∈{4,8,N _(symb) ^(PUCCH)}.T _(RI)=4·M _(SC) ^(PUCCH).

In a second embodiment, HARQ-ACK is allowed to multiplex over allsymbols of selected PUCCH. When UE transmits CQI bits or rank indicator(RI) bits together with HARQ-ACK bits, it shall determine the number ofcoded symbols Q′_(UCI) for CQI or rank indicator as

$\begin{matrix}{Q_{UCI}^{\prime} = {\min\left( {{{ceiling}\left( \frac{O_{UCI} \cdot M_{sc}^{PUCCH} \cdot N_{symb}^{PUCCH} \cdot \beta_{offset}^{PUCCH}}{O_{{HARQ} - {ACK} - {REF}}} \right)},T_{UCI}} \right)}} & (2)\end{matrix}$where O_(UCI) is the number of CQI bits including CRC bits or RI bits;O_(HARQ-ACK-REF) is the HARQ-ACK codebook size dynamically indicated bymeans of the corresponding DCI formats detected by UE. Alternatively,O_(HARQ-ACK-REF) may be the number of HARQ-ACK/SR information bitsincluding CRC bits. The meaning of other symbols in equation (2) is sameas in equation (1) above. More specifically, T_(UCI) may not be definedfor calculating the number of symbols for CQI information. The value ofT_(RI) may be 4·M_(SC) ^(PUCCH) as above. For CQI information:β_(offset) ^(PUCCH)=β_(offset) ^(CQI)/β_(offset) ^(HARQ-ACK),for RI bits:β_(offset) ^(PUCCH)=β_(offset) ^(RI)/β_(offset) ^(HARQ-ACK), andfor HARQ-ACK informationQ′ _(HARQ-ACK) =N _(symb) ^(PUCCH)·β_(offset) ^(PUCCH) −Q′ _(RI) −Q′_(CQI).

In a third embodiment, when UE transmits CQI bits, SR bits or rankindicator (RI) bits together with HARQ-ACK bits, it shall determine thenumber of coded symbols Q′_(UCI) for HARQ-ACK, or rank indicator as

$\begin{matrix}{O_{REF} = {{O_{{HARQ} - {ACK}} \cdot \beta_{offset}^{{HARQ} - {ACK}}} + {O_{RI} \cdot \beta_{offset}^{RI}} + {O_{CQI\_ MIN} \cdot \beta_{offset}^{CQI}}}} & (3) \\{Q_{{HARQ} - {ACK}}^{\prime} = {\min\begin{pmatrix}{{{ceiling}\left( \frac{O_{{HARQ} - {ACK}} \cdot M_{sc}^{PUCCH} \cdot N_{symb}^{PUCCH} \cdot \beta_{offset}^{{HARQ} - {ACK}}}{O_{REF}} \right)},} \\T_{{HARQ} - {ACK}}\end{pmatrix}}} & (4) \\{Q_{RI}^{\prime} = {\min\left( {{{ceiling}\left( \frac{O_{RI} \cdot M_{sc}^{PUCCH} \cdot N_{symb}^{PUCCH} \cdot \beta_{offset}^{RI}}{O_{REF}} \right)},T_{RI}} \right)}} & (5)\end{matrix}$where O_(HARQ-ACK), O_(RI) is the number of HARQ-ACK/SR bits includingCRC bits and RI bits respectively; O_(CQI-MIN) is the number of CQI bitsincluding CRC bits assuming rank equals to 1 for all serving cells forwhich a periodic CSI report is configured. For CQI and/or PMIinformation:Q′ _(CQI) =N _(symb) ^(PUCCH)·β_(offset) ^(PUCCH) −Q′ _(RI) −Q′_(HARQ-ACK)

In another aspect of the present disclosure, a method is provided for aUE to decide whether to transmit P-CSI information together withHARQ-ACK/SR and RI coded symbols on a PUCCH in a same TTI. A ratio of anamount of resources required for transmission of the HARQ-ACKISR and/orRI information in the PUCCH over a total amount of resources availablefor transmission of the control information in the PUCCH is determinedby the UE. More specifically, a cell domain and/or time domain HARQ-ACKbundling may be first performed before calculating the aforementionedratio. Then, the CSI information is transmitted together with theHARQ-ACK and RI information in the PUCCH resource by the UE, when theratio is less than or equal to a threshold value. Otherwise, UE shalldrop or suspend the CSI information transmission.

In one embodiment, at stage 5010 of FIG. 5, HARQ-ACK encoded symbols maybe mapped to symbols starting from those consecutive to RS of PUCCHchannel in increasing order of first symbol index in time domain, thenthe frequency index, starting from the lowest frequency index in theselected PUCCH resource. While CQI symbols is mapped in a time-firstorder from the beginning of the physical resource blocks assigned fortransmission of selected PUCCH. Additionally, the HARQ-ACKJSR symbolsmay puncture CQI symbols starting from the lowest frequency index (i.e.first embodiment) or may perform rate matching around the CQI and RIsymbols e.g. in the second and third embodiment above.

In one embodiment, an offset value Δ may be introduced to adjust thecode rate of different UCIs by splitting the reserved bits forHARQ-ACKJSR and P-CSI bits in case of concurent transmission. In moredetails, assuming the total payload size of PUCCH format is S, then thetotal bits for HARQ-ACKJSR bits rate-matching equal to ceiling (S/2)+Δ,while S−ceiling(S/2)−Δ space is left for P-CSI bits rate-matchingoperation. The offset value(s) Δ may be signaled by higher layerssemi-statically or dynamically indicated through DCI formats or acombination of them.

In one embodiment, the channel coding schemes for multi-CCs periodicchannel quality information (CQI and/or PMI), HARQ-ACK and rankindication may be configurable by higher layers. Either scheme 1 orscheme 2 as described above may be employed.
